Course description and aims

We discuss the structure and dynamics of the Earth's interior based on a combination of limited observations and laboratory experiments. We also discuss the formation and evolution of our planet, with its connection to the origin and evolution of life. In addition, we have to consider planet formation processes in general, in order to explain the observations of our solar system and exosolar systems and understand the ubiquity and diversity of planetary systems. Planet formation is a multi-step process involving a variety of physical phenomena. It is important to understand 1) the initial conditions of planet formation such as the dynamical / thermal structure and viscous evolution of proto-planetary disks and 2) the basis for planetary growth such as orbital evolution and coalescence growth processes of small bodies.
About half of lectures are given by non-Japanese professors in English.

Student learning outcomes

[Goals] Learning the basics of Earth's interior and planet formation, and understanding the outlines of cutting edge science on related topics.
[Topics] We discuss the formation and evolution of Earth based on an understanding of present-day structures and dynamics in the interior of our planet. In addition, we learn the dynamical / thermal structure and viscous evolution of proto-planetary disks and the orbital evolution and planetary growth processes in order to understand our solar system and exosolar system.
